Specification of Letters Patent.

Patented June 25, 1907.

Application filed March 23, 1907. Serial No. 364,114.

.To all whom, it may concern:

Be it known that 1, CHARLES BROWN, a citizen of the United States, residing at Canton, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Window-Sash-Operating Devices; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing, making a part of this specification, and to the numerals and figures of reference marked thereon, in which- Figure 1 is a perspective view showing different parts broken away. Fig. 2 is a detached view of the operating crank. Fig. 3 is a transverse section of the Window-sash operating shafts, showing the same properly connected, showing one of the pimons and its worm gear in proper relative position. Fig. 4 is a similar view looking toward the left Fig. 1.

The present invention has relation to devices for operating window-sashes, and it consists in the novel arrangement hereinafter described and particularly pointed out in the claims.

Similar numerals of reference indicate corresponding parts in all the figures of the drawing.

In the accompanying drawing, 1 represents the window frame, which is of the ordinary construction. The lower sash 2 and the upper sash 3 are arranged to move up and down in the grooves or ways of the usual construction. Below the frame 1 is located a chamber in which are located the shafts 4 and 5, which shafts are journaled in the brackets 6, said brackets being securely fastened to the window sill 7 or its equivalent, which window sill of course constitutes a portion of the window frame proper. To the window sashes 2 and 3 are attached the bars 8 and 9, which bars are provided with the heads 10 and 11; the bars extend through the elongated slots 12 formed in the vertical members of the window frame proper which are for the purpose of providing a means for locating the heads 10 and 11 in a suitable chamber or boxing formed upon opposite edges of the window frame proper. Upon the shafts 4 and 5 are located the gear wheels 13 and 14 which gear wheels are securely attached to the shafts 4 and 5. The worm gears 16 and 17 are journaled in the brackets 18, which brackets are connected to the sill 7 or its equivalent. The worm gears 16 and 17 are so located that they will mesh with the gear wheels 13 and 14, and when rotated, rotary motion will be imparted to the shafts 4 and 5. The shafts 4 and 5 are provided at their opposite ends with the sprocket wheels 19 and 20 around which sprocket wheels are located the chains 21 and 22, which chains are arranged substantially as shown in Fig. 1. To the chains 21 and 22 are attached the cables or cords 23 and 24, which cables or cords are connected at their opposite ends to the heads 10 and 11. To the heads 10 and 11 are attached the cables or cords 25 and 26, which cables or cords extend over the ulleys 27 and 28 and thence downward and their opposite ends connected to the chains 21 and 22. pulleys 27 and 28 are held to the top or upper portion of the window frame cap 29 or its equivalent by means of the housings or sheave blocks 30.

It will be understood that when the worm gears 16 and 17 are rotated the chains will be actuated by means of the sprocket wheels 19 and 20, and when it is desired to elevate either sash the proper shaft isrotated in the direction to pull upon the cords 25 and. 26, which pulling action elevates the window sashes. It will be understood that either sash can be elevated reference being had to the particular worm gear to which the crank 31 is attached. After a given sash has been elevated it will be held in elevation by reason of the worm gears 16 and 17 holding the pinions 13 and 14 against rotation.

desired to lower the window sash the particular worm gear is rotated in the direction to move the chains 21 and 22 in the proper direction to permit the moving down of the sash. The bars 8 and 9 are journaled in the heads 10 and 11 so that said bars 8 and 9 constitute pivotal points for the window sashes 2 and 3, thereby providing a pivoted window proper and a sliding window. When it is desired to lock the Window sashes against springing or pivotal movement the ordinary catch bars 32 are employed, and are connected in the usual manner. Owing to the fact that the catch bars enter the elongated slots 12 they will not interfere with the vertical movements of the window sashes, but will hold said window sashes against swinging movement during the time their outer ends are engaged with or entered with the slots 12.

Having fully described my invention what The When it is I claim as new and desire to secure by LettersPatent, is

1. In a window sash operating device, a window frame sashes movable in the frame, bars located intermediate the tops and bottoms of the window sashes, said bars eX- tended through slots formed in the window frame and provided with heads, shafts journaled below the window frame, said shafts provided with sprocket wheels, chains located around the sprocket wheels, elevating cables or cords connected to the chains and to the heads, and means for rotating the shafts, substantially as and for the purpose specified.

2. In a device for o crating window sashes, the combination 0 a window frame, sashes located therein, said sashes provided with bars located intermediate their top and bottom ends, heads secured to the bars, shafts located below the window sashes, said shafts provided with gear wheels and sprocket wheels respectively, chains located around the sprocket wheels, cords connected to the chains and to the heads, pulleys adapted to support the cord above the head, said pulleys located in the upper portion of the windowframe and means for rotating the shafts, substantially as and for the purpose specified.

3. In a device for o crating window sashes, the combination 0 a window frame,

sashes located therein, said sashes provided with bars and the bars provided with pivoted heads, said bars located intermediate the top and bottom ends of the sashes, shafts located below the window sashes, said shafts provided with gear wheels and sprocket wheels respectively, chains located around the sprocket wheels, elevating cords connected to the chains and to the heads, pulleys adapted to support the cords, said pulleys located in the upper portion of the window frame, means for rotating the shafts, and means for locking the window sashes against swinging movement, substantially as and for the purpose specified.

4. In a window sash operating device, a window frame, sashes adapted to move in a vertical plane in the frame, said sashes provided with bars located intermediate their ends, said bars provided with pivoted heads, shafts located below the window frame, means for rotating the shafts, sprocket wheels mounted upon the shafts, and means for elevating the sashes by the rotation of the sprocket wheels, substantially as and for the purpose specified.

In testimony that I claim the above, I have hereunto subscribed my name in the presence of two witnesses.

CHARLES BROWN.
